JAMES TREES, OF GREENSBURG, PENNSYLVANIA.

' Letters Patent No. 67,613, dated August 6, 1867.'

IMPROVEMENT IN HOSE-NOZZLES.

T0 ALL WHOM IT MAY CONGERN:

Be it known that I, JAMES TREES, of Greensburg, in the county of Westmoreland,.anl State of Pennsylvania, have invented a new and useful Improvement in Hose-Nozzles, of which the following is a full, clear, end exact description, reference being had to the acconipanyimr` drawings, which make part of this specification, und in which- Figure 1 represents a. longitudinal central section through my improved nozzlev Figure 2, a. transverse section through the same, at the line :z: :v of iig. 1.

Figure 3, a view of the tip or point of the central cone detached, and

Figure 4 a view of' the modified form 'of the same.

It is the object of my invention to discharge the water from the nozzle in a smooth, solid stream, and to the greatest practicable distance with a given amount of force or pressure, and to this end my invention consists in combining with a pipe or nozzle of unif'cirm taper, a cone placed centrally within the pipe, so as to'form an annular water way.

To carry out my invention I make the pipe A in two sections a a', united by a screw or other proper. coupling, andtapering uniformly from the `entrance to the exit at an angle of aboutve degrees. Concentrically within the pipe I places. cone, B', of corresponding taper, commencing with a fine point at the nozzle of the pipa-and running about three-fourths 'of-its length. .Amore abrupt cone, B, of about one-third the length of cone B', Ais placed with its base against the other and in the same axial plane,`so as Vto taper to a point at the entrance of the pipe. The cones are sustained in place by slender supports Z1, which offer but slight obstruction to the current. These supports or-braces are secured to the cone and slip into notches in the pipe, as shown in fig. 2. The long cone is divided into two sections b1 b2, united by a socket joint or other properV connection for the purpose of removing or replacing the tip of the cone. Fig. 4 shows a cone of less inclination, which may, under some circumstances, advantageously be substituted for the other.

I have found 4,by experiment `that the water, issues from a-pipe, such as described, in the form of a. hollow cone, and that the pressure of the atmosphere tends to compress -the stream to iill this hollow, and thus produce a smooth, solid stream.

What I claim as my invention, and desire to secure by Letters Patent, is

Thecombination, substantially in the manner described, with a pipe or nozzle of uniform taper, of two cones arranged base to base concentrically within the pipo.

Invtestimony whereof I have hereunto subscribed my name.
